WIRE CLAMP.

Specification of Letters Patent.

Application filed November 19, 1912.

Patented May 19, 1914. Serial No. 732,312.

To all whom it may concern:

Be it known that I, WILBERT D. HENDER- soN, a citizen of Canada, and aresident of the city and county of San Francisco, State of California,have invented a certain new and useful Improvement in Wire Clamps; and Ido hereby'declare that the following is a. full, clear, and exactdescription of the same, reference being had tothe annexed. drawings,making a part of this specification, and to the letters marked thereon.

The object of the present invention is to provide a device which willfacilitate the construction of buildings in which metal channels areused.

' In the accompanying drawing, Figure 1 is a side View of the device;Fig. 2 is an edge view thereof; Fig. 3 is a sectional view of a. metalchannel and wooden block connected by my improved device, the deviceitself being shown in side elevation; Fig. 4 is a similar View in whichthe wooden block is secured to the opposite side of the channel fromFig. 3.

On referring to the drawing, it will be seen that my improved deviceconsists of a stiff spring wire clamp .1, shown in Figs. 1 and 2 in itsinoperative position. 'l'n Figs. 3 and 4 it is shown in its ope 'ativcposition, in which it engages a wooden block 2 and a metal channel 3,the arrangements of the channel relative to the wooden block being thereverse of one another in Figs. 3 and 4. The clamp comprises a terminalportion A, which lies close against one edge of the metal channel 3, asshown in Figs. 3 and 4, a mediate portion B, which extends along theoutside ofthe bottom of said channel in Fig. 3, or across said channelin Fig. 4, a

'ininal portion, said latter comparatively long central portion C whichextends along the edge of the channel opposite to A, and also along oneside of the wooden block 2, a short mediate portion E which extendsalong the side of the wooden block 2 opposite to the channel 3 and aterminal portion F having a sharp point that enters the wood in saidside. The long central portion is at right angles to the mediate portionB but, in its inoperative position, makes an obtuse angle With themediate portion E, as shown in Fig. 1, the mediate portion E makingsubstantially a right angle with the terminal portion F.

In using the clamp, it is passed around the wooden block and metalchannel placed together, and pressure is applied to force the sharppointof the terminal portion F into the woodeirblock, when it assumesthe position shown in Figs. 3 and 4.

I claim A wire clamp consisting of a single piece of stiff wire having acomparatively long central portion, two short terminal portions and twomediate portions of different lengths respectively between the centraland terminal. pol-thins, the longer mediate portion being at rightangles both to the central portion and to its adjacent terminal portion,and the shorter mediate portion making an obtuse angle with the centralportion, and a right angle with the adjacent tertcrminal portion havinga pointed end.
